Summary

FOR TEMPERATURES EXCEEDING THE SPIN EXCITATION DEGENERACY TEMPERATURE, BUT LESS THAN THE MEAN KINETIC ENERGY PER ATOM, THE THERMAL CONDUCTIVITY OF LIQUID HELIUM 3 IS PROPORTIONAL TO THE TEMPERATURE, WHEREAS THE VISCOSITY DEPENDS ON IT WEAKLY. IN A BROAD RANGE OF TEMPERATURE AND MOLAR VOLUME THE THERMAL CONDUCTIVITY AND VISCOSITY ARE CHARACTERIZED BY A SCALING DEPENDENCE OF THE TEMPERATURE. AT HIGH TEMPERATURES THEY INCREASE WITH GROWTH OF THE LIQUID DENSITY. RELATIONSHIPS ARE OBTAINED WHICH RELATE THE KINETIC COEFFICIENTS OF HELIUM 3. THE MEAN KINETIC ENERGY PER HELIUM 3 ATOM IS DETERMINED.
